The year, day by day
Summer here tops out rather than builds: the warmest normal high is 82°F around July 8, short of 90°F on every date, while 135 dates carry a normal low at or below freezing, the coldest 18°F near January 22.
The freezing stretch
The normal low stays at or below 32°F into March 30, then returns to freezing around November 17, covering 135 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
April 15 carries the biggest normal gap between afternoon and dawn, 23°F between the normal high and the normal low.

Data-derived climate profile
How Millport's climate pattern fits together
heating led · mid swing
Millport's energy balance leans toward cold weather: 6,096 annual heating degree days against 615 for cooling. Its 44.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Millport's frost-free season lasts about 164 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Millport's middle-range seasonal profile. The measured spread is 44.9°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Millport's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Millport's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Millport, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Millport's primary station: MILLPORT 4 NE (USC00335315). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Millport; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Millport comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
